Network communication between VM´s on same host does it it "stay" inside the host

$

Hi

I need to be 100% sure that network communication between VM´s located on one and the same of our HyperV hosts. This is to rule out our network equipment is the cause of some issues.

Does somebody here knows how to check? I´ll really appreciate it :-)

Hyper-V Console not connecting to Local Server/Displaying any Virtual Machines

$

Hi,

So I've spent the past 2 days searching the web for an answer with lots of similar problems, but nothing that directly correlates. My scenario is, I have a windows server 2012 instance used as a virtual host that is running around 10 VM's. 

Last Friday, everything was fine. I logged into SCVMM yesterday morning to check our VM's across the network to find that one particular host was "Host Not Responding", i logged into the host itself to see whats going, bringing up Hyper-V manager to find that all of my virtual machines weren't displayed, nor was the local server in the console pane. In a blind panic I quickly checked that I could remote onto one of the server's that is hosted on the effected host - I could. So with everything seeming to run fine, i composed myself and started to wonder what has happened. There are no error logs, nor error messages when trying to open hyper-v, it just seems to sit doing nothing (with the snap-in loaded). 

Google quickly tells me that the .xml file corresponding to the VM's has become corrupted and therefore i'll need to remove the suspect parts of the .xml config to make them "reappear" in the console pane. I'm not hugely experienced with reading .xml but everything i can find in google that's apparently the "corrupted sections" of config aren't within my .xml files - leading me to believe that they aren't actually corrupted. 

I have tried to restart the Hyper-V management service to no avail, I have not restarted the host as if that doesn't fix the problem and I cannot restart the VM's that are running on this host then i will have a huge problem, so i'd like to fix this issue without restarting the host. 

Nothing happened that I am aware of over the weekend that could of caused this, it seems to be completely random with no events or errors to support any foul play. 

One thing i did notice, on my other hosts, i do not have .xml files, on each of the other hosts i have .symlink files instead. 

please help! 

Regards,

Dale 

Virtual machine IOPs calculation

$

Hi all,

I am aware of the great new tools/techniques with Server 2012 R2 that allow for easy per-VM IOPs information gathering but am wondering if anyone has a good way to get such information on a Server 2012 (NON R2) clustered VM environment? Basically, I am hoping to get per-VM IOPS information; if that doesn't make sense or more information is needed, please let me know, thanks!

Any information/breadcrumbs would be greatly appreciated!

"Mouse Not Captured In Remote Desktop Sesion" in Hyper-V

This is a silly little problem, but on my 2008 server I installed a Hyper-V virtual machine (a Win 2008-64 system), and I can't get it to capture the mouse.

Integration services are installed and the mouse is listed but I can't capture it.  I've tried Ctrl Alt right arrow.....

I'm used to VmWare and this is my first time with Hyper-V.

 

error 0x8000FFF in hyper-v windows 2008 server R2

$

Hello,

here is my problem: when I start my VM, I receive the error "fail to restore" with ID 0x8000FFFF.

I tried to apply the fix described in this page: https://support.microsoft.com/en-us/kb/2960802

However, the command "Net start vmhostagent" returns the error "invalid service name".

Is it because it only works on a windows server 2012 R2?

If I execute the command "Net stop vmms", it works, but my VM still sends the error 0x8000FFFF at start.

Do you have any idea of what I could do?

Thanks!

Disk drive suddenly went missing in Virtual Machine

$

So at the end of last week, the users in one of the office said one of the network drives was not working.

I log onto the server and look, sure enough one of the drives is completely missing. So I shut the virtual machine down.  Check the settings, yes the missing drive is still configured and pointing to the VHD file.  So I run ChkDsk on the vhd file, no problems found.  I restart the virtual machine, still missing.  So I turn off the virtual machine, expand the size of the missing VHD which completes successfully according to the messaging.  Restart the virtual machine, drive is still missing. So now I head to the event viewer to find the error messages.  I can not find any ( any tips on what to search for? ) I looked through admin logs, system logs, any log I could think of, with no luck on any events about not being able to load the VHD file.

What are next steps for trouble shooting this issue?  Should I try removing and adding using a different SCSI number?

Any thoughts or help would be greatly appreciated.

Hello

I have a problem with running Hyper-V (MS Windows Server 2012 R2) in a KVM environment.

KVM is installed on a Ubuntu 14.0.04 LTS. The HyperV-VM has the vmx-Flag set, Model: Sandy-Bridge).

VT-X is enabled...

I installed Hyper-V with the command:

Invoke-Command -ScriptBlock { Enable-WindowsOptionalFeature -FeatureName Microsoft-Hyper-V -Online; Restart-Computer 

Creating machines is no problem, but I can't start them.

Error: 'test' failed to start. (Virtual machien ID xxxx) The Virtual Machine Management Service failed to start the virtual machine 'test' because .....

In Device Manager everything seems to be good. Theres also "Microsoft Hyper-V Virtualization Infrastructure Driver" installed.

See output of Get-NestedVirtStatus.ps1-Script:

http://fs5.directupload.net/images/160316/htvvuc4c.png

I made also a test with the HyperV Server 2012 R2. The installations works fine, but same error on starting machines....

Does someone know why this error occurs?

Thx for your help.

Best regards

Multiple AVHDX files for only one snapshot...

$
0
0

Hello together,

we have multiple Hyper-V-Servers on a Windows Server 2012, and we are using the snapshots feature for all of them.

But only one Hyper-V-Server is creating multiple AVHDX subfiles for only one snapshot. All other servers creating one new AVHDX file for every new snapshot. In the screenshot below you see a part of the files for only 2 snapshots of the "problem-server".

The Hyper-V-Server with the problem is a Windows Server 2012R2 with MSSQL2014 Server.

All our Hyper-V-Servers have nearly the same configuration in the Hyper-V-Manager.

And if we create a new snapshot, at this particular time.this is the only snapshot. There are no overlapping creations of other snapshots.

If you need more information, pls contact me.

VM connected at 10MBps

$

Hello,

I have a two node hyper-v host cluster and the Ethernet cables for the virtual networks are connected to 1GBps switch ports. Due to performance issues with a VM our network group ran a test to see what speed a virtual machine connected to the switch at and determined that it was connected at 10MBps. Looking at the network adapter on the VM it shows as being connected at 10GBps. We mapped a drive to the server and copied a file. We were seeing about 1MBps file transfer speeds. 

Is there a way on the server to determine the actual speed at which a VM connects or hard code the network adapter to connect at a certain speed?

Hyper-V replication fails every night

Dear All,

I use Hyper-V replica for months on different VMs (SQL without logs or high availability options... / IIS / RDS ...).Several weeks ago I started to have replications error on SQL VMs every night at 0h01

I have enough bandwidth and the antivirus has been removed to be sure it is not the cause.

Once the replication is broken a resume-vmreplication is not enough and  I have to resynchronize the VMs... and it works until the next night.

In the EventViewer I get 3 consecutives error : 33680, 32086, 32022

My SQL server VMs are not using log shipping, mirroring or AlwaysOn. Just use different VHD for datafiles and for logfiles.

Please advise.

Failed to connect to virtual machine

I have a 3 node failover cluster running Windows Server 2012R2 Datacenter edition. I have an iSCSI box connecting the 3 with about 12 VM's. On node 1 and 2 I can within the Failover Cluster Manager right click on a VM and click connect and connect to the VM. From either Node 1 or 2 when I attempt to right click and click on connect to any VM's on node 3 I recieve the following error (Failed to connect to virtual Machine 'Machine Name'). If I open the Failover Cluster Manager on node 3 I can right click and click connect to any VM on any Node and it works fine.

Now that being said with VM's running on node 3 users are able to connect to virtual server and access services and resources on it like normal.

Hyper-V VM Dynamic Memory on - Demand and Status are empty

I have two Windows 7 SP1 machines running on the same Server 2012 R2 Hyper-V host (in a failover cluster). They have the latest updates and integration services. The two have the same hardware settings. 

However, one of them shows a value for dynamic RAM demand and status of OK, but the other has empty for memory demand and status.  I restarted the Win 7 desktop, but it didn't help.  Why is it not reporting?  I have a feeling it won't expand either if needed.


Remote management Hyper-V

Ls,

After a few nights i'm offically beaten by Hyper-V and remote management.
Working on a lab for MCSA.

Information infra;

Desktop -Range: 192.168.1.0  | Workgroup
Lab -Range:172.16.16.0 |  Workgroup

Hyper-V installed -> VM's booted up.

Following i'm able to do.

-Ping from all sides.
-PSSession's to VM's
-RDP to VM's

Unable to do the following :

Take over any server hosted on the Hyper-V infra with RSAT Windows 10 Tools.
WSMAN setup, Trusted ip's entered, even stopped Firewall, Cmdkey credentials, restart-service winrm, i think i tryed it all..

Opening Hyper-V manager on the desktop -> adding the server and credentials -> 
Gives me a warning about delegation of control on the VM has to be set?

Do you want to set Yes / No   ( Prompt keeps coming back when selecting Yes) 

Desktop is installed in a different language, so it's harder to find the error message.

Anyone able to tell me just in a few steps what should be the correct way? 
Shouldn't need to be this hard i hope..... alternative i can only think about is making a bastion server on the Hyper-v host and install RSAT tool on this client and control the rest of the vms via this client.

Thanks,

Mark

server 2012 r2 partmgr disk errors

I have a new Dell server. Been in operation for 7 weeks or so. Suddenly getting numerous s channel errors and partmgr disk errors. The system suddenly rebooted itself out of the blue 2 days ago and is becoming more unstable as we go. Dell supposedly remoted in and took a look and said it is not a hardware issue. I was not present when this happened. Anywa, any insight would be greatly appreciated. Here is more info. I have pages of the following errors. I am not running any virtual machines. This system was migrated over from a virtual machine.

VM Console Shows "CTRL+ALT+DEL" Instead of "Installing Updates" Progress

Host: Windows Server 2012 R2 Standard with Hyper-V role

Guest VM: Windows Server 2012 R2 Standard

When I choose to update the child VM by clicking "Install Updates and Reboot" when I connect the console to watch the VM, I don't see the expected "Installing Updates, 1 of 30" progress screen that I see on a physical Windows host.  I instead see the "Press CTRL+ALT+DEL to sign in" screen.  The console is, of course, unresponsive to CTRL+ALT+DEL because it's actually installing updates (I can confirm this because if I wait long enough, it will eventually reboot with updates installed).  But I can't watch the progress to make sure it's proceeding normally and not hanging. Interestingly, the clock continues to count forward, so it's not like it's a frozen image.  It's just not showing me the progress update.

Is this normal or did I inadvertently apply some policy that's causing this?  If it IS normal, is it a bug?  I don't remember Hyper-V 2008 R2 doing this.
